This CFW was tested on most PS3 Models by different testers and no problems were encountered. But as any CFW release you must install it with caution and by following proper instructions, No one will be held responsible for any damage caused.

For details about Updating from CFW3.55/4.21 to CFW4.30 Please read the Update Guide below

For details about Downgrading back to CFW/OFW3.55 Please read the Downgrade Guide below

PSN/SEN access is available as long as the current "passphrase" still the same.

Loading games from App_home Icon is now fixed.

It was tested by hundreds of testers on all PS3 models (FAT & Slim) and no problems were encountered.

It can run games signed with Keys up to version 4.30 without any Eboot/Sprx patching needed

Games can be loaded from Disc Icon (with Original game in BD) and from app_home (Disc-less, but not all games).

Current 3.55 homebrew applications can't be loaded on this CFW, applications must be re-signed properly for FW4.21/4.30

ATTENTION:

1- This CFW doesn't have LV1 checks disabled and can't be installed on Downgraded PS3 consoles unless you have Dehashed/Reset Syscon Properly (if you're not sure about your PS3, Dehash it anyway to avoid any risk) Link: Dehashing Tutorial

2- Always make a NOR/Nand dump using multiMAN or memdump before installing any CFW to have a recovery backup in case of any bricks. Having a valid NOR/Nand dump is an essential step before upgrading, because you will always have a way to recover (using hardware flashers) when you have a valid dump.

** A Hardware Flasher alone without a valid dump may not fix your bricked PS3 **

Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP"

While on Rogero CFW4.30, go to System Update from XMB and install the Downgrader PUP.

After the Downgrader PUP installs you'll be on a hybrid CFW3.55 that will still shows ver4.21/4.30 from system settings.

Enable QA flag by following these steps:

1- Download the Rebug QA_Toggle package from here: toggle_qa.pkg
2- Put the "toggle_qa.pkg" on USB and Install it on the PS3.
3- Run the "Rebug Toggle QA" from XMB, the screen will go Black and you will see HDD Led activity then if all went fine you will hear 2 or 3 Beeps and the PS3 will Restart back to XMB.
4- If you want to make sure QA flag was set, go to "Network Settings" then apply the following key combo (all at the same time):

L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down

You should see Edy Viewer, Debug Settings, and Install Package Files if done correctly.

Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP"

Swap the current HDD with the New HDD, Turn the PS3 on, follow screen instructions and let it install the Downgrader CFW.

After the Downgrader CFW installs you'll be on a hybrid CFW3.55 that will still shows ver4.21 from system settings.

I'm sure Rogero know his thing, but don't install this yet until we know:

VERY IMPORTANT: Can you install future CFWs on this CFW? in other words, is it modified to accept 3.55 signed PUPs because ofw 4.21 obviously doesn't if this doesn't do that, you''ll be stuck on this FW without a hardware flasher. unable to install future CFW.

so if you don't have a flasher, DON'T INSTALL. It should work but we don't know about the future yet.

1- This CFW doesn't have LV1 checks disabled and can't be installed on Downgraded PS3 consoles unless you have Dehashed/Reset Syscon Properly (if you're not sure about your PS3, Dehash it anyway to avoid any risk)

2- Always make a NOR/Nand dump using multiMAN or memdump before installing this CFW to have a recovery backup in case of any bricks. Having a valid NOR/Nand dump is an essential step before upgrading, because you will always have a way to recover (using hardware flashers) when you have a valid dump.

3- It's always better to have QA flag set (leave it Enabled) on your PS3 for safer upgrading/downgrading operations.
4- Always use the Recovery Menu while installing this CFW to avoid possible bricks (XMB update works, but Recovery Menu is safer).
5- TB CFW users must update back to OFW 3.55 before installing this CFW to avoid possible bricks.

v1.00 Info

This is a 4.21CFW spoofed to version 4.25 to allow SEN access

It can be used as a normal System Update from any 3.55 OFW/CFW/MFW

It was tested using a hardware flasher and no bricks or any problems at all were encountered

It can run games signed with Keys up to version 4.21 without any Eboot/Sprx patching needed

Games must be loaded from Disc Icon (with Original game in BD) and not from app_home

Current 3.55 homebrew application can't be loaded on this CFW, applications must be re-signed properly.

Downgrading back to 3.55 is always possible using the following steps:

Once the install is finished, you're now back on Rogero CFW3.55 v3.7 (from here it's better to dehash again before installing any other OFW/CFW 3.55)

Credits to eussNL and the PS3 Dev wiki for the valuable and always up-to-date source of information. Credits to Deank for his continuous efforts on Multiman and many other PS3 tools/fixes. You need to already be on 3.55 to install this. Installing from any firmware other than 3.55 will simply not work.

PS3 Dehashing/Syscon Reset Tutorial for Downgraded Consoles

For all owners of PS3 consoles downgraded from 3.55+ using hardware flashers and Rogero_CFW_v3.x

To "Dehash the PS3" (Reset the syscon) and have the PS3 back to normal safer mode like any original ( non Downgraded ) PS3, here are the steps :

1- After completing the downgrade process and having Rogero CFW 3.x up and running, make sure you have the Blu-Ray drive attached or the QA Toggle package won't work.
2- Download the Rebug QA_Toggle package from here (toggle_qa.pkg)
3- Put the "toggle_qa.pkg" on USB and Install it on the PS3.
4- Run the "Rebug Toggle QA" from XMB, the screen will go Black and you will see HDD Led activity then if all went fine you will hear one Beep and the PS3 will Restart back to XMB.
5- If you want to make sure QA flag was set, go to "Network Settings" then apply the following key combo (all at the same time):

L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down

You should see Edy Viewer, Debug Settings, and Install Package Files if done correctly.

6- Now that you have QA flag set, Turn Off your PS3 and Turn it back on but into "Recovery Menu"

This Step is very important, it have to be from "Recovery Menu" and not a normal Update from XMB or the PS3 will Brick.

Here is how to access it:

a. Turn off PlayStation 3.
b. Turn it on and keep Holding The power button down; The system will turn on and turn off once again.
c. Once the System has been shutdown, Turn it on again and keep Holding The power button down (you will hear 1 beep first, keep holding) until you hear 2 consecutive beeps
d. When you hear the 2 beeps take finger off power button.
e. You will be prompted to plug in your controller via usb and then hit the PS button
f. The Recovery menu will pop up.
g. Last Option #6 is what you must use "System Update"

Alternatively you can simply use CondorStrike's Updater package to enter Recovery Menu directly from XMB without going through the boot sequences. Download: Condor Updater v2.0

7- Now you must have any 3.55 OFW or CFW with original (non Patched) LV1 in your "USB:\PS3\UPDATE\PS3UPDAT.PUP", here's a link to 3.55-Kmeaw. Download: Kmeaw355.PUP

8- Select the last option of the Recovery Menu --> System Update, then when prompted press and hold "Start+Select" for 5 seconds to start the update.

Once finished the PS3 will restart into XMB with the Syscon hashes reset back to 3.55 in both "ros0" and "ros1" and your PS3 is back like any original/non Downgraded PS3 that can use any CEX/DEX Fw without having to worry about disabling LV1 checks.

For anyone who have bricked with Green Light and Black Screen, you can try entering Factory Service Mode using a PSGrade Dongle (any old jailbreak dongle flashed with the PSGrade hex file)

Insert the dongle then start the ps3 with (Power then Eject) and if the PS3 shuts off by itself after few seconds which means it entered FSM (Factory Service Mode) you can try inserting a USB stick with the proper "LV2diag.self" + 3.55downgrader.PUP used in the first days of downgrading, if things went right, this could fix the Brick... it worth testing... Please if anyone bricked and can test this method post back the result...

Finally, Raiyou (via bbs.duowan.com/thread-29238182-1-1.html) has posted what is believed to be the problem PS3 models (pictured below) that are bricking as a result of specific boards, mainly JSD as well as having a base version of 3.50 and above including the CECH2025's that have never been downgraded and are still getting bricks.
